The Portuguese was fined £10,000 for his sarcastic appraisal of officials following the Premier League loss to Sunderland and failed in an appeal over an £8,000 penalty imposed after the defeat at Aston Villa.
Mourinho may address the punishment in Friday's pre-match media conference ahead of Sunday's concluding match of the season at Cardiff.
Following the charges in relation to the Sunderland match, Mourinho suggested he was being victimised and that the Football Association had lost its sense of humour.
"Every time I speak there is a consequence," Mourinho said.
"Even if I say that a referee was amazing that was a reason to be with a charge.
"I can't say the truth. I don't feel free at all. If you want a better press conference, speak with the FA."
Asked about the British sense of humour and sarcasm, Mourinho said: "So Mr Bean is in jail..."
Mourinho lost his 77-match unbeaten home league record when Sunderland won 2-1 at Stamford Bridge.
Following the match, which saw his assistant Rui Faria sent to the stands and later given a six-match stadium ban, Mourinho refused to answer questions, instead making a statement in which he congratulated his Chelsea players, Sunderland and then moved on to the officials.
He described referee Mike Dean's performance as "unbelievable" and "fantastic", before moving on to referees' chief Mike Riley, saying "what they are doing during the whole season is fantastic, especially in the last couple of months, especially in matches involving the teams that were in the title race, it's absolutely fantastic".
It was found that Mourinho's comments, in themselves, did not question the officials' integrity, but amounted to disrepute and improper conduct.
A FA statement read: "While the commission did not find that Mourinho's post-match comments called into question the integrity of the referee appointed to the above fixture and/or the integrity of Mike Riley, general manager of the Professional Game Match Officials Limited, they did find that the comments brought the game into disrepute and the charge for improper conduct was found proven."
The Portuguese also was unsuccessful in an appeal against his £8,000 fine for his conduct towards referee Chris Foy at the end of a defeat at Villa Park in March.
Mourinho has been sanctioned three times this season for brushes with authority, the first coming against Cardiff in October when he was sent to the stands and later fined £8,000.
He was the third member of Chelsea's staff to be punished following the Sunderland match after Faria and midfielder Ramires, who received a retrospective four-match ban, ending his domestic season, for striking Sebastian Larsson during the loss.
